(t.

The receptacle g to be. lilled is mounted upon the scaley pan y' beneath the filling` head a, and the end y'Z of the beain g (which is fulcrnined at g) is arranged to operate a contact maker or breaker to cause the breitliine or mal-'ling ol" an elect cuit as hereinafter dcserihcd. This ycontin't maker hre- :er cons' oiled at in heal digs. 141 and l5 are. side elevation and planv 'switch it', fuse box and plug fc3, thc wire l beine thereafter connected to the bearinvs 7 2 C T3 While its other Dart or continuation la passes from the cup i through the plug le" 'to the f are the electro-magnets?, sai

electro-magnets f and then to the contact piece ci. lThe Wire 21s connected through. the plug k and lamp l2@ (or othcrerpuvalent resistance) to said. contactpiece si and also to the lever rlhis lever is mov-ed hy a rod d3 'Fused to the plate ci.

The actions of the .machine i? lows z-On an empty receptacle g bei placed on the scale pan g and the switch r/ operated to supply a current ci electricity from the mains, an electric circuit is com leted from the plug .lea through the wire l,

earings h2, lever il', the mercurial contact its, wire 1", electro-magnets f, contact piece lever d2 'and wire 2 back to the plug This causes the electro-magnets f to immediately raise the armature vd and consequently the valve in the Yfilling head c and so supply liquid to the receptacle g. This movement o the armaturealso raises the Contact lever cl2 thus breaking the contact between it and the part t' (see Fig. 4) in this manner causing the current to pass from the electro-magnetsf through the lamp lc to the conductor 2. l he lamp lr thus absorbs any excess of current that might otherwise ini ure the other arts of the apparatus, and the current wil pas therethrough until the receptacle g received. it )predetcrini l quantity oi liquid by the v; .t oi' which it causes the beam g3 to 'oscillat` g2 raises the end. it of the iev r la, c with the mercury in the receptacle is this breaks the circuit, on which the the head -o is allowed to he closed l spring. l

ln 'orrn o? machine whe is closed by the electro-rn pletion oi the filling operatic s indie c is raised by the toot o.' tlirough the treaclle lever m2, rod ma and 'the lever in is crum'efl at m5 to the pillar m and aan h 1s connected to said spindle iln spin-file retained in its raised position o" controlled bolt n which takes heueatn the plate m7 of the lever mi and is cennfthe armature n. Mounted upon the elette 'd plate fand hy he fran c the other parts bein? supported.

workin, and over al these pa cover o, The bolt n cover o and has a screwed nu espesa upon outer end. The withdrawal of the boit n oy the movement of the armature n on the completion of an electrical circuit as hereinafter described allows the lever m4 to be lowered by gravity or the actions of a spring.

ln making use oi a current of electricity of high electromotive force or high tension,`l connect the ends of the conductors 3 and 4 to the wall bracket lr or lam i socketor connection o. One of them 3) is then connected to the fuse box k2 and passes therefrom through the plug connection k3 to the terminal 02. To the terminal o3 is connected the remaining part 3a of said conductor 3 which b the plug connection o4 passes to the termina of to which is connected the cond -ctor 3b. vWhen. the lever 'mJl is in its raised position a stud m8 fixed therein makes contact with the conductor 3" said stud beingconnccted to the electro-magnet f through the flexible connection or wire 3C. To the other end of the electro-magnets f is connected the Wire 4 which passes to the plug connection les and thence to the wall bracket k or lamp connection o. The terminal o3 is connected to the electro-magnets o51 which are supported by the framework o upon which is also mounted the strip or contactmaler o7. it will thus be seen that when the lever m4 is in its raised position the supply valve will he open for the supplying of liquid to the receptacle g and that upon the weight of liquid in said receptacle causing the end g2 of the balance g3 to move or raise the strip o" into contact with the electro-magnets o5 and stud oS an electrical circuit will be complcted. through the parts above described and that the electro-magnets f will be energized thus causing the armature n to with draw the bolt from beneath the part m7 of the lever m4 in this manner allowing it to fall ing awa when inaliing use oi accumulatore B as the source oi electrical enerffy, l arrange the f nncctions as shown ny Fig. 11 so that on receptacle g having received its supply of h i i the strip o7 is raised into contact with ie screw o9' and electro-magnet o, two elecioal circuits are completed, one in shunt with the other, the primarv or main circuit passing iron/i the terminal Q9 through the conductor 5 to the terminal g, through the screw o8 (which is insulated from the coils om), the strip o7, framework o, terminal gg, conductor 5a terminal g2, conductor through the coiisf to the terminal g3, then by the conductor 5? to the stud ms, and forward through the conductor 5d to theterminal g, thence through the conductor 6 to theterminel p of 'the battery B. The shunt circuit extends from the strip o7 through the connection o9 'to the coils o, then by Way of the plates c, c and the conductor 5e, terminal g3, through the conductor stud m8 a'nd conductor 5d to the terminal g4. TLhe magnets f will by these means be energized, the bolt n withdrawn, and the circuit. b'roken as hereinbefore described.

By rotating the nutr adjusted in position or it may be withdrawn from projecting beneath the lip m7 so that the machine' may be used Without the employment of theelectrical devices hereinbeore described for causing the closing ofthe valve. In this latter form of machine in.- stead of making use of the kind of circuit closing and breaking devices as illustrated by Figs. 10 and 11, I mayemploy a "mercurial contact device, similar vto that shown by Figs. 12 and 13 and as hereinbefore described,

- however in this case I arrange the outer end k7 of the lever h to take through an opening gsin the beamv g3 (see Figs. 14 and 15) so that the rising of said beam on the receptacle. g having received its desired quantity of liquid will cause the part ha to be moved into the mercury in the cup h4 thus completing the circuit as desired to cause the withdrawal of the bolt n from beneath the part m7 as hereinbefore described.

I divide the tank b into two compartment b2 and b3 by means of the partition b* and within the part b3 I mount the ball or float s upon the lever s fulcrumed at s2 and carrying a plate or sluice valve s3 which covers an opening made in the 'partition b4" so that the level of the water in the compart ment b3 is kept constant.

-My im roved devices or portions of them are equally applicable to ap aratus wherein the anfount of liquid to be fi led into the receptacle is regulated by the weight thereof and wherein the vcircuit is completed or broken by the arm of a scale pan or balance,

-as illustrated byA the accompanying sheets of drawings, or to apparatus in which the circuit is completed on the liquid in the receptacle having reached a predetermined height, when the electrical through such liquid.
